Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed May 23, 1819. Serial No. 299,205.

To all whom it may concern:

. Be it known that I, EDWARD F. HAPPEN- SACK, a citizen of the United,States of America, and a. resident ofCinciimati, in the county ofHamilton and State of Ohio, have invented new and useful Improvements inPliers, of which the following is a specification.

My invention relates to pliers for use particularly in working withchains such as pump chains. In such uses it frequently is necessary toincrease the size of the links of the chains in order to couple them tovarious parts of the pumps.

The object of my invention isto increase the spreading capacity of apair of pliers without increasing the spread of the tool.

This object is attained by the means described in the specification andillustrated in the accompanyin drawing, in which Figure 1, is a si eelevation of'a pliers embodying my invention.

Fig. 2, 1s a similar view of a pliers embodying my invention but showingit in a different position.

Fig. 3, is a perspective view of a pliers embodying my invention showingit entering a link of small diameter.

Fig. 1, is a view similar to Fig. 3,'but showing the pliers in positionto spread the link shown in Fig. 3.

Fig. 5, is a view similar to Fig. 4, but showing the liers with the linkspread as indicated'in ig. 4, pre aratory to spreading it to a stillgreater egree.

Fig. 6, is a perspective view showing my pliers in position to compressa link.

The tool has the usual lever arms A, A, fulcrumed together at a, andshaped so as together to form a tapered nose.

The nose terminates in lu a a Spaced from the lugs a, a are Iiigs a a,which form an enlarged seat for the reception of a ring or link to bespread to a greater extent than it could be spread by the smaller seat,formed by the In s a, a

In use if one desires to spread a llnk from a small to a large diameter,he first inserts the nose into the link so that the smaller seat engagesthe inner periphery of the link. After having spread the link to thefull capacity of the smaller seat, he inserts the nose farther into thelink so that it takes into the larger seat formed by the lugs a, a, andthen spreads the link to the size desired.

I provide the lever arms with the usual internal seat a by seating thelink in which it may be compressed, as shown in Fig. 6.

What I claim is A pliers having a tapered nose terminating in lugsforming a seat and having spaced from said lugs other lugs formmg anenlarged seat for a ring to be enlarged.

In testimony whereof, I have hereunto subscribed my name this 21st dayof May, 1919.

EDWARD F. HAPPENSACK.
